HUMIIDIFYI1\TG DEVICE FOR INTERNAL-COMBUSTION ENGINES.

Application filed. November 17,1924. Serial No. 750,404.

This invention relates to appliances for internal combustion engines, and more particularly to what I term a humidifying device for internal combustion engines;

One of the main objects of the invention is to provide simple and efficient means which can be readily applied to an internal combustion engine and will generate steam in such manner as to supply the same to the intake manifold so as to provide a moist explosive mixture. A further object is to provide a device of this character which can be applied to the exhaustmanifold of the engine in such manner as to utilize the heat generated in the exhaust manifold for heating water to generate steam to be used in the cylinders. Further objects Wlll appear from the detail description.

In the drawings Fig. 1 is a perspective view of the device indicating its use;

Fig. 2 is a section taken substantially on line 22 of Fig. 1;

Fig. 3 is a section taken line 33 of Fig. 1.

The device includes a sheet metal tank 1 substantially on provided with a concaved bottom wall 2- which is inclined from one end of the casing and is adapted to fit about the upper portion of exhaust manifold a of an internal combustion engine A. At each end tank 1 is provided with adepending clamp 3 which inclucles an inner section 4: secured to the tank and an outer section 5 hinged at 6 to the tank, each of these sections being provided at its lower end with an offset tab 7 and these tabs having registering openings for receiving a securing screw 8. This provides simple and efficient means whereby the tank is effectually secured upon the exhaust manifold so as to fit about the upper portion thereof.

A bafiie plate 9 extends across tank 1 at approximately the vertical center thereof and terminates a short distance from one end of the tank, this baffle plate being provided with a flange 10 which is inclined downwardly toward the adjacent end wall of the tank. The tank is provided, through its top wall with a filling neck 11 which is exteriorly threaded for reception of a closure cap 12.

l/Vater poured through neck 11 will be directed by flange 10 into the water space below bafiie plate 9. Space 13 above the baffle plate" is a steam spacein which steam generated in the tank collects this steam being conducted to the intake manifold?) by means of a tube 14: which communicates at. its upper end with space 13 ad acent the top wall of tank 1, this tube being provided at its lower end with av valve 15 of known construction the outlet end of which projects intointake manifold J). The tank is further provided with'a regenerate steam which will collect within the steam space 13 from which it is discharged I into intake manifold b by means of tube 14 and valve 15, this steam acting to produce v retain an explosive mixture containinga suitable.

proportionv of water in vaporous form which will act to increase the expansive efliciency of the explosive mixture and will also prevent, to a great extent,the forming of carbon in the engine cylinders. As this device utilizes the heat generated in the exhaust .manifold for heating the water there is no expense attached to itsoperation and the device itself can be easily produced and applied at small cost, thus providing a device of simple and inexpensive construction which can be readily applied and will act to materially increase the efiiciency of operation of the engine to which it is applied. that I claim is i In a humidifying device for an internal combustion engine, a tankadapted for seating upon the exhaust manifold of the engine, a baflie extending across the tank from one end thereof to within a short distance of the other end of the tank and dividing the interior of said tank into a lower water compartment and an upper steamfspace, said bafiie being provided at its inner end with a flange extending above the bafiie and insplashing onto the upper surface of the clined downward toward the adjacent end of baifle, an outlet tube connecting with the the tank, thev tank being provided with a steam space of the tank, and means for con- 1 filling neck above the flange, said flange acttrolling discharge of steam from said tube.

- ing to direct into the water compartment In testimony whereof I affix my signature.
